Security Relearn

Before beginning, a security relearn must be performed to ensure all systems are set up correctly. The security light should be off before proceeding.

Common Problems After ECM/PCM or BCM Replacement

• -Code P0315/P1336 After Replacing the ECM/PCM
  When replacing the ECM/PCM, the vehicle’s crankshaft position system must be relearned to ensure accurate engine timing and operation. If this procedure isn’t completed, Diagnostic Trouble Codes (DTC) P0315 and P1336 will be triggered, which can prevent the engine from running smoothly.
• -Code B1001 After Replacing the BCM
  A new BCM requires proper integration with the vehicle’s security and restraint systems (SDM). Without this setup, you’ll encounter DTC B1001, which affects the airbag system and could disrupt normal vehicle operation.
